Voyager 2 Hourly Plasma Parameters, Interplanetary Solar Wind

NSSDCA ID: SPHE-00487

Availability: At NSSDC, Ready for Electronic Access

Time span: 1977-08-22 to 2006-02-02

Description

This collectiont contains hourly average key parameters for interplanetary cruise data acquired by the Voyager 2 Plasma Science (PLS) experiment. The data are written in ASCII format and provided in files named V2_HOUR_yyyy.ASC, each covering one year of data for year "yyyy". The file V2_HOUR.FMT gives the data record format. Each record includes year, day, hour, proton speed (km/s), proton density (#/cc), proton thermal width (km/s), where proton temperature T(eV) = 0.0052(width)**2, and alpha density (#/cc), as well as proton bulk speed and vector components (Vr, Vt, Vn) in the RTN coordinate system. In RTN the R axis is outward from the Sun to the spacecraft, T is the cross product of the solar rotation axis and R, and N completes the orthogonal system. All parameters are derived from a nonlinear fit calculation. A parameter E1 (if present) gives the sum of currents for electrons. These cruise data were obtained from the MIT Plasma Group's anonymous FTP site at mit.space.edu/pub/plasma and were accompanied by spacecraft SEDR ephemeris data cataloged at NSSDC under data set ID 77-076A-00I.
